Why High-Voltage NEVs Require Advanced PP Insulation Boards and Films

The rapid development of new energy vehicles (NEVs) toward high-voltage systems—commonly 800V and above—brings forward new expectations for insulation materials. In this context, PP insulation boards and PP insulation films are facing elevated technical demands.

1. Evolving Role of PP Insulation Boards in NEV Batteries

Today, PP insulation boards are essential in high-voltage battery systems, providing robust electrical insulation. They must now withstand higher voltages and temperatures without compromising mechanical strength or safety. Their applications extend to battery separators, junction boxes, and high-voltage component casings.

2. PP Insulation Films for Space-Saving Designs

As NEV manufacturers aim for compact battery packs, PP insulation films help achieve space-efficient insulation. These films, placed between high-voltage layers, must provide superior dielectric properties and flame retardancy in thinner formats.

3. Enhanced Material Properties Required

  • High Dielectric Strength: PP insulation boards are now designed to tolerate extreme voltage stress.

  • Flame Retardancy: PP insulation materials must meet stringent automotive fire safety norms (UL 94 V-0).

  • Dimensional Stability: Insulation must maintain form under heat and pressure within battery systems.

4. Industry Certifications and Standards

Compliance with ISO 6722, UL 94, and IEC 60695 is mandatory for both PP insulation films and boards in NEV components, ensuring global market acceptance.

5. Eco-Friendly and Recyclable Options

To align with green manufacturing goals, new PP insulation boards incorporate recycled content without compromising performance. Innovations include lightweight films with improved heat resistance.

Conclusion

With the push toward high-voltage NEVs, both PP insulation boards and PP insulation films must evolve to meet emerging technical, safety, and environmental requirements. They are now fundamental to the next generation of electric mobility.
